Robot

Robots are being used predominantly in the wood processing. Robots are especially interesting for the increase of productivity in the manufacturing. In fact though, robots can master health-damaging or physically-charging tasks without a problem. Also, they take over monotone tasks like loading, commissioning, turning, stacking or sorting.

In contrary to conventional machines, the robot is not restricted to tasks. It's easily adjustable to new products and thus can take over several tasks.

In the woodworking industry, robots are e.g. used for or for feeding milling moulded parts.

control

Machines for the execution of manufacturing and handling tasks. They are equipped with multiple CNC controlled axes and with tools or gripping elements. The movement of the roboter is programmed or controlled by an operator like a CNC-controlled machine. Through the familiar CNC-environment, experienced CNC-operators can program and control robot systems-

Distinguishing by the kinematics

The robots are distinguished by their kinematics. The kinematics describes the movement of points and bodies in their space. It's being distinguished between parallel kinematics and serial kinematics At the serial kinematics, it's to distinguish between articulated robots and gantry robots. In the woodworking industry, articulated robots and gantry robots are being particularly used.

In the woodworking industry, jointed robots and portal robots will be applied first and foremost.

History

1954 The worldwide first industrial robot, the Unimate, is invented by George Devol. He obtained the patent in 1961.
1966 The Norwegian Ole Moloch develops the first hydraulically-driven lacquering robot, the Trafalla TR 2000.
1970's First robot with electrical drive are put on market.

97: Describes the rotation direction of a rotating, cylindrical machine part (e.g. planer, feed roller, glue roller, metering roll, application roll, ..)) in relation to the workpiece or another part of the machine. Here, 'up-cut' means that the movements of the parts do not lead to a common feed direction.

Milling tools, planer heads

The cutting movement of the tool is opposed to the feed movement of the workpiece. The cutting of the wood does not start with the blade hitting the workpiece, but only at the beginning of the upward movement of the blade. Before, the blade's edge scrapes and pushes. During the upward movement, the cutting process begins. The resulting chips are elongated and their thickness increases.

Advantages

  • Longer tool life
  • because the pressure on the blade is slowly starting to arise, starting from the main cutting edge.
  • by pre-dividing: The cutting process begins parallel to the direction of the fibers, thus the wood is divided before the actual cut. The blade has a shorter way of action than when milling in down-cut.
  • Tool drive power savings by pre-dividing
  • Allowed for manual feed and mechanical feed

Disadvantages

  • For disadvantageous fiber directions, pre-dividing can lead to rough surfaces and increase the risk of avulsions.

Application

Because of its economic advantages with regard to the tool life, the main part of the chip removal processes on woodworking machines is done in up-cut. Nevertheless, in order to achieve good cutting quality and prevent avulsions, down-cut spindles are used.

29174: Software module for product managing and procedure optimising in industries and crafts business. Order data can be imported from different systems. (e.g. woodCAD|CAM).

Software for production planing, data distribution and process optimization.

For an optimal organization of the production process woodFactory will be deployed in industrially finished companies and producers, which manufacturer furniture in lot size-1-production. Here the woodFactory offers efficient tools for production planing, for generating production data and documenting as well as controlling the production progress.

Central tasks of the production planing is the flexible forming of production batches. For this, components of one or several orders considering the available production capacity are being rounded up together to production batches or are being distributed to batches. woodFactory facilitates companies with a high vertical range of manufacturers, who e.g. have to assign their components to different production routes, to plan their production orders time-delayed. The plan takes here the given delivery dates and the technical manifestation of the components into consideration.
